TL;DR: Reliable synthetic and measurement strategies for plasmonically coupled nanostructures with ∼1 nm gap, in which both the nanogap size and the position of a Raman-active molecule in the gap can be controlled with nanometer/sub-nanometer-level precision, can address important issues regarding the synthesis and optical properties of pl asmonic nanostructure, including structural and signal reproducibility.

TL;DR: The principles and findings shown in this paper offer the fundamental basis for the thiolated DNA-based chemistry in forming and controlling metal nanostructures with ∼1 nm plasmonic gap and insight in the optical properties of the plAsmonic NNPs, and these plasMonic nanogap structures are useful as strong and controllable optical signal-generating nanoprobes.

TL;DR: The molecular beacon mercury(II) ion sensor was amenable to regeneration by simply unfolding the ferrocene-labeled DNA in 10 microM cysteine, and could be regenerated with no loss in signal gain upon subsequent mercury( II) ion binding.

TL;DR: The enantioselective recognition of 3,4-dihydroxyphenylalanine using penicillamine-modified gold nanoparticles with one enantiomeric ligand has been investigated.

TL;DR: Electrochemiluminescence efficiency and radical stability of pyrene, a poor ECL luminophore, are markedly improved as the number of peripheral multidonor units increased in a series of compounds.
